To all whom it may concern:

Be it known that I, LEMON L. OSBORN, a citizen of the United States,residing at Portland, in the county of Multnomah and State of Oregon,have invented certain new and useful Improvements in HydraulicWVater-Motors, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to hydraulic motors, more particularly to thatclass of motors in which the alternate ascending and descending offloats arranged in two tanks is utilized to develop power for variouspurposes.

Another object of this invention is the production of a hydraulic motor,which is simple in construction, efficient in operation, and consists ofa comparatively small number of parts.

A still further object of the present invention is the production ofnovel means for alternately opening and closing the inlet and outletmeans for facilitating the operation of the motor.

With these and other objects in view this invention consists of certainnovel construc tions, combinations, and arrangements of parts as will behereinafter fully described and claimed.

In the drawings: Figure 1 1s a perspective view of my device, looking atthe front end of the same. Fig. 2 is a perspective view of the rear endor outlet end of the motor. Fig. 3 is a longitudinal section taken online 33 of Fig. 1.

Referring to the drawings by numerals, 1 designates the body of themotor, which comprises tanks 2 and 3, in which tanks are adapted to workfloat valves 4 and 5. Brackets 6 are formed upon the body 1,intermediate the tanks 2 and 3 and a shaft 7 is journaled therein. Beams8 are fixedly secured to said shaft intermediate their ends and are,preferably, positioned at right angles thereto, and said beams carry ateach end a journal member 9, which engages the upper ends of theconnecting rods 10, which rods are secured, at their lower end, to thefloats 4 and 5. Therefore, it will be obvious that as the floats 4 and 5are raised and lowered within the tanks 2 and 3 the beams 8 will becaused to rock, thereby irnparting motion to any driving means, whichSpecification of Letters Patent.

may be connected to the beams 8 in any suitable manner.

An operating arm 11 is fixedly secured to the shaft 7, and a rod 12 issecured to the outer end of the arm 11 and works in an aperture 13 inthe outer end 14 of the link member 15. The rod 12 is providedintermediate its ends with a washer or collar member 16, which memberlimits the movement of said rod within said aperture 13 and said rod 12is also provided, at its lower end, with an enlarged head portion 17which prevents the displacement of said rod from said link 15. It willbe obvious that as the shaft 7 rotates in one direction so as to causethe outer end of the arm 11 to move downwardly the rod will readily passthrough the aperture 13 of the link 15 and cause the collar 16 to comein engagement with the outer end 14 of the link 15 and as the armcontinues to move, it will cause the outer end 14 to be presseddownward. On the other hand, when the outer end of the arm 11 is causedto rise upwardly, the enlarged lower end 17 will be brought intoengagement with the link 15 thereby causing the end 14 of the link 15 tobe raised and impart rotary movement to the shaft in the oppositedirection to that previously stated.

The link 15 is keyed. to the shaft 18, and as above stated impartsrotary movement to the same through the medium of the link member 15 andthe arm 11. Brackets 18 are supported upon the tanks and said bracketssupport journals 14 in which journals are journaled the ends of theshaft 18. A plurality of arms 19 are also keyed to the shaft 18, some ofwhich extend in opposite directions to the other, preferably, twoextending rearwardly and two outwardly. To the arms extending rearwardlyare connected link rods 20, which rods are connected, at their lowerends to the outer ends of the door-locking levers 21, which levers arepivotally secured at 22 to the flange 23 secured to the body of themotor 1. The lever 21 is provided upon its under surface with a con cavenotch portion 24, which is adapted to normally engage protruding ends ofthe shaft 25, which shaft is secured to the hinged doors 26, andnormally holds said doors in a closed position. The doors 26 are hingedto the flanges 23 by means of a rod 27 which has its ends journaled insaid flanges and hinge members 28 are fixedly secured to the door andsaid rod and thereby hingedly secure said doors to the same. The doors26 are provided with a bulged portion 29 through which passes the shaftwhich is provided with outer ends 25 adapted to be engaged by the notch24 of the locking lever 21. The arms 19, which extend upwardly areconnected to the locking levers 21 in a similar manner as previouslydescribed. It will be obvious that when the shaft is rotatedright-handedly the levers 21 controlling one of the doors will beraised, as shown in Fig. 2 and the levers 21 will engage the shafts ofthe other door and hold the same in a locked position, as also shown inFig. 2. However, when the shaft is rotated in the opposite direction theother door will be unlocked and the door which has been previouslyopened will be locked in a closed position after the water has beendischarged from the tank having its exit through the opening closed bysaid last-mentioned door. It will be obvious that as soon as the lookinglevers 21 are raised the force of the water contained within the tankwill readily throw the doors to an open position, thereby allowing thewater to flow out through the opening.

A link member 30 is also fixedly secured to the shaft 18, and said linkmember has a link connection 31, which is also connected to a linkmember 32, which is keyed to a shaft 33, which is adapted to operate therotatable valve or inlet member hereinafter described. Brackets 34 aresupported upon the sides of the body of the motor 1, and carry, at theirupper ends, journals 35 in which is mounted a shaft 33. An arm 36 isfixed to the shaft 33 and is connected, at its outer end, to a linkmember 37, which link member 37 is connected, at its lower end to an arm38, which arm is keyed to a shaft 39 upon which are fixedly secured thevalve members 40 adapted to alternately close and open said inletopenings, as hereinafter described.

Chutes 41 are secured to the front of one end of the body of the motor1, and direct the water into the inlet openings. The inlet openingscomprise a substantially circular valve casing 42, in which is mountedthe valve member 40, which is adapted to close the opening 43 formed insaid valve casing 42.

One of the valve members is adapted to close the front end of the valvecasing 42 and the other valve is adapted to close the rear end and itwill be obvious that when the arm 38 is swung downwardly the shaft 39will be rotated, which will cause the valve member 40 to rotateright-handedly, thereby closing the front end of one of the casings andcutting oif the flow of water therethrough, which movement will throughthe medium of links 30 and 31 cooperate with the shaft 18 allowing therear door communicating with the tank 2 to open, thereby allowing thewater to flow out through the same and empty the tank 2. When the valvepreviously stated is closed the other valve will be opened thereby,allowing the other tank 3 to be readily filled, thereby causing thefloat 5 to rise, and as the water is emptied out of the tank 2, causethe float 4 to lower, thereby imparting an oscillatory movement of thebeams 8. \Vhen the arm 18 is swung in the opposite direc ti-on or swungupwardly the valve 44 Will rotate in the opposite direction and open,thereby allowing the water to flow therethrough and fill the tank 2,causing the float 4 to rise, and the valve 45 will close, thereby,through the medium of the link connec tions 30 and 31 opening the reardoor communicating with the outlet "opening and causing the tank 3 to beemptied and the float 5 to be lowered.

From the foregoing description, it will be readily seen that in theapparatus as specified, the beams 18 will be caused to oscillate throughthe medium of the rising and lowering function of the floats 4 and 5. Itwill also be obvious that when one inlet valve is open in one tank, theoutlet valve will' simultaneously be closed, and when the inlet valve isclosed the outlet opening will be simultaneously opened, therebyallowing the tanks to be quickly and readily filled and emptied.

The shaft 33 has connected, at each end, the links 36 and 37 forallowing the rotation of the shaft 39 and the operation of the valves 40and 44 to more easily take place.
